Based on GCOSM, the objective of the paper is to propose an approach to investigating optimal pavement preservation strategies (OPPSs) for road networks in a systematic manner. In the following sections, the methodological procedure for investigating OPPSs of road networks is first presented, which is followed by a case study demonstrating the applicability of the proposed procedure. The HDM-4 system is employed as an OES in the study for Vietnamese national road network.

A prototypical problem road agencies are faced with is to find the optimal application schedule of maintenance works for a given road section. To solve such problems what-if models such as the road transport investment model (RTIM), the highway economic requirements system (HERS), and the highway development and management tool (HDM-4) are widely used to predict the consequences of different maintenance options.
